Joshua 22:20

“Did not Achan the son of Zerah, etc.] One that descended from Zerah the son of Judah, (<060718>Joshua 7:18); commit a trespass in the accursed thing; in taking what was devoted to sacred uses: and wrath fell on all the congregation of Israel? and which was what was feared now; and this instance is brought to show that such fears were not groundless: and that man perished not alone in his iniquity: which seems to confirm the notion of those who think that his children suffered with him; though it may be observed, that it was through his sin that thirty six men were slain by the men of Ai, (<060705>Joshua 7:5).”

“Of Zerah - That is, one of his posterity. Not alone - But brought destruction upon his whole family, and part of our forces sent against Ai. Joshua 22:22”

“22:20 Achan: See ch 7. The delegation of western tribes feared that Achan’s sin and its consequences would be repeated.”

“Jos 7:1, Jos 7:5, Jos 7:18, Jos 7:24; Co1 10:6; Pe2 2:6; Jde 1:5, Jde 1:6 Joshua 22:21”

“He finally reminded them of the sin of Achan, how that had brought the wrath of God upon the whole congregation (Josh 7); and, moreover, Achan was not the only man who had perished on account of the sin, but thirty-six men had fallen on account of it at the first attack upon Ai ( Jos 7:5). The allusion to this fact is to be understood as an argument a minori ad majus, as Masius has shown. "If Achan did not perish alone when he committed sacrilege, but God was angry with the whole congregation, what think ye will be the consequence if ye, so great a number, commit so grievous a sin against God?" Joshua 22:21”
